pecification of Letters Patent.

Patented Oct. 5, 1920.

Application filed December 28, 1918. Serial No. 268,714.

T 0 all w from it may concern.

Be it known that I, ERNST V. HILL, a subject of the King Sweden, residing at WVorcester, in the county of lVorcester and Commonwealth of Massachusetts, haveinvented a new and useful Improvement'in Coin-See lee-tors, of which the following, together with the accompanying drawings, is a specification.

The present invention relates to devices for separating standard coins of a predetermined denomination from counterfeits, slugs, washers, and other spurious disk-like bodies of generally similar dimensions. The present improvements are applicable to the type of coin selector fully illustrated and described in the United States Letters Patcut to Keith, No. 1,236,870, dated August 1 1:, 1917, and also in my copending application Serial No. 261,797, filed November 9, 1918.

The present invention embodies, in addition to the fundamental principles of the selector set forth in my aforesaid copending application, certain novel principles relating to the accurate measurement and calipering of coins that are especially useful in connection with pieces of twenty-five cent denomination, both of the old and the new nited States coinage. In common with the machines'of the Keith patent and my aforesaid copending application, the machine of the present invention is constructed on the duplex principle, 2'. 6., being so designed as to accept standard coins of the same denomination, but of two different sets of di mensions. The machine of the present invention diifers from the machine of my aforesaid copending application only asregards the construction, arrangement, and principle of operation of the several coin measuring and calipering instrumentalities, and consequently, the description and drawings of the present application will be confined, as far as possible, to the instrumentalities wherein such differences exist.

Figure 1 is an enlarged vertical section illustrating the coin measuring and calipering instrumentalities that constitute the essence of the present invention.

*ig. 2 is a section on line 2 2, of Fig. 1. Like reference characters refer to like parts in the different figures.

The detector mechanism in the present vided in the machines of the Reith patent and my aforesaid copending application. The ends of said pendulums are adapted to cooperate with suitable sets of wards and recesses carried by a pair of valve controlling levers 8, 8, one adapted for movement in the case of a standard coin of one set of dimensions, and the other adapted for movement in the case of a standard coin of the same denomination, but of a difierent set of dimensions, as in the machines of the Keith patent and my aforesaid copending application.

Said levers 8, 8, are operated upon by a spring 9 and at their ends are normally in engagement with a cam 10 on shaft 11, the rotation of which is communicated to the movable barrel 3 by means of a connecting link 12, sleeve 13, spring 14, and plate 15, in precisely the same manner as described in the Keith patent and in my aforesaid c0- pending application. The position assumed by the pendulums 4:, 5, and 6, 7, and also the positions assumed by a pair of thickness pendulums, not shown, that are controlled by the cooperating annular knife edges 16 i of said barrels 2 and 3, are the determining application. On the other hand, if the coin 1s spurious or does not correspond to either of the two sets of dlmensions contemplated by the machine, neither of the levers 8, 8, is

allowed to move, and the valve 17 is held in such a position as to reject said coin. The instrumentalities which constitute the subject matter of the present invention and to which the movements of the several pendulums are delicately responsive, Wlll. now be ders'20 of; said barrels; These plungers 18 contain the sets of measuring instrumentalities that make contact withthe. two faces of the coin when the latter is received between them, said coin being centered with respect to said plungers by means of a sliding block 21, carried by barrel 3, and said coin being gripped in said centered position by the knife edges 16, 16, precisely the same as in the machines of thelieith patent and my aforesaid copending application.

Each plunger 18 contains an inner slidable plunger mechanism which is constituted by a? plurality of annularly arranged plun-' ger sections or segments 22, the latter 'pre-' senting an annular series of knife edges 23. Each plunger segment 22 has a flange portion 24 that bears against a' shoulder 25 .of plunger 18, being yieldinglyv held against said shoulder by means of a series of springs 26, operating on studs 27 that pro ect outwardly from said flanges 24. The springs.

26 are confined at their outer ends in recesses provided in. plates 28 that close the end of each barrel 2, 3.

Inwardly of the segmental plungers 2 2 is disposed an annular plunger or sleeve 29, the periphery of which is provided'with' a plurality of longitudinal slots adapted to receive an annular series of pins 30. Threaded or otherwise secured to said sleeve29, so as to cover and inclose said'slots is a sleeve 31, which has a flange 32 adjacent and on the outer side of flange 24. Said flange 32 is apertured for the passage of the studs 27.

' Each pin 30 is provided with ahead 33, norpinging against the various measuring edges mally held in contact with the end of sleeve 29 by'means of an inwardly pressed pin 34 that carries aspring 35 operating between a shoulder v36 thereon and the plate 28.

Said pins 34-take bearing in a flange 37 of another sleeve 38 that. is disposed within the sleeve 29. Each flange 32 carries a stud 39 which passes freely through the adjacent flange 37 and makes contact with an adjustablescrew 40 carried by a lever 41'that is pivoted at 42 in plunger 18. As in the ma: chines of the aforesaid Reith patent and my aforesaid copending application, said levers.

41,41, are utilized to control the positions of one set of pendulums 6. 7, the longer arms of said levers projecting through slots in the barrels'f2,13, and being operated upon by springs43. i

The sleeve 38 projects rearwardly from a sleeve 38 is adapted normally to engage a shoulder 47 of plunger 18, owing to the con tact with. said flange of a flange 48 that is carried by a member 49 .in which the center pin 46 is secured. Said member 49 is pressed inwardly by means of a spring 50 operating against plate28.

The flange 37 of sleeve 38 carries a member 51 that serves as a bearing for a lever 52, the latter being pivoted at 53 in said member 51 and carrying an adjustable screw 54 that makes contact with the flange 48.

The two levers 52 whose longer arms project through suitable openings in the barrelsQ, 3, and are operated upon by springs 55, serve to control the positions of the pendulums 5, in a manner similar to that set forth and described in the Keith patent, and in my aforesaid copending application.

The flange 48 carries an adjustable screw 56 that normally makes contact with the flange 32 of sleeve 31.

In addition to the mechanism above set forth each plunger 18 has slidably mounted therein a pluralityof studs 57, here shown as four in number, to the ends of which is secured a concentric coin guide 58 in surrounding relation to the knife edges 23. Said coin guide 58 is normally maintained at the limit of its inward movement by springs 59, the other ends of which bear against flange 32 of sleeve 31. The limit of inward movement of the coin guide 58 is determined by heads 60 on the studs 57, which heads engage the shoulders of counterbored holes in the plunger 18. The springs 59 pass through suitable clearance holes in the flanges 24 of sectional plungers 22. The object of providing these inwardly pressed guiding members 58 is to prevent the coin, as it is dropped into the selector, from imnamely, in the position adapted to direct the coin into the compartment reserved for spurious or counterfeit pieces. The levers 8, 8, are prevented from moving under the action of spring 9, either because they are in engagement with the concentric part of cam 10, or because the ends of one or more of the pendulums 4, 5, 6, 7, and the thickness pendulums, not shown, are opposite and in contact with the wards or projections carried by said levers.

Upon rotation of shaft 11 through slightly more than a quarter of a revolution, the barrel 3 begins to move toward the barrel 2, it being noted that the movement of said shaft is transmitted through link 12 to the sleeve 133, spring 14, and plate 15, which latter first acts through spring 62 to move the block 21 toward the barrel 2, and thereafter acts to bodily move the barrel 3 in the same direction. This primary movement of the block 21 causes it to receive within its central cavity the coin which has been arrested in its passage through slot 61 by the arresting mechanism, not shown. The subsequent movement of the barrel 3 with its knife edges, pins and other measuring instrumentalities into engagement with the coin occurs while the shaft 11 is so moving that the link 12 is approaching a horizontal position, or during the first half of the forward movement of crank 63 on said shaft. As said movement is continued through its last half, the link 12 operates to retract the barrel 3, and the arresting mechanism, not shown, is thereupon retracted from the slot 61 so as to permit the gravity descent of the coin into the valve 14. As the barrel 3 begins its movement toward the barrel 2, by force applied through plate 15, the knife edges 16 are brought into engagement with the outer part of the coin just inside of its rim or flange, thus firmly gripping and holding the coin within the cylindrical cavity of block 21. The engagement of these knife edges with the coin determines the amount of inward movement of barrel 3, and as described in the Keith patent and in my aforesaid copending application, a pair of thickness pendulums, not herein shown, since they form no part of the present invention, are made responsive to this movement in such a manner as to permit the lifting of'either one of the levers 8 if the thickness thus measured corresponds to the predetermined standarch-provided of course the other pendulums 4, 5, and 6, 7, will permit of this movement. These other pendulums are con trolled as above stated by the novel coin measuring instrumentalities above described of the barrels 2 and 3, the action of which will now be set forth in detail.

The segmental knife edges 23 of plunger sections 22 are pressed inwardly against the opposite faces of the coin for variable dis tances, depending upon the'relief of the coin at the different parts of the circle engaged by said knife edges. In other words, the various plunger sections 22 will occupy different relative longitudinal positions when their respective knife edges are in contact with the face of the coin; one of these plungers will obviously take up a position deterplunger portion 22 which is farthest held outwardly by the maximum relief of the coin acts through its flange 24, bearing against flange 32, to force the stud 39 outwardly. The movement of stud 39 is trans 'mitted to the adjustable screw 40 to rock the lever 41 about its pivot, this applying obviously to both levers 41, and thereby controlling either the pendulum 6 or the pendulum 7, as the case may be.

Also, this plunger portion 22 which is farthest moved outwardly acts through its flange 24, bearing against flange 32, to move the stud 56 outwardly. The flange 48 to which said stud is secured, responds to this movement and thereby through adjustable screw 54 rocks the lever 52 about its pivot, this applying obviously to both levers 52, and thus affects a control of either the pendulum 4 or the pendulum 5, as the case may be. It will thus be seen that the maximum relief of the coin on the circle engaged by the sectional knife edges 23 results in a control of both sets of pendulums 4, 5, and 6, T.

On the other hand, that plunger portion 22' which is least moved outwardly, as determined by the minimum relief of the coin. on the circle engaged by sectional knife edges 23 assumes a position which permits a limited movement of plunger 18, under the action of springs 19, which tend to keep the shoulder 25 in contact with flange 24. This outward movement of plunger 18 changes the position of the pivot points 42. Obviously such a change in the positions of the pivot points of the levers 41 results in a variation of the movement of the long arms of said levers that would not otherwise occur, and consequently the control of the pendu lums 6, 7, is aflected accordingly. From the above, it will be seen that the minimum relief of the coin on the circle engaged by the knife edges 23 results in a control of either the pendulum 6 or the pendulum T, as the case may be. There is thus produced, in connection with the sectional knife'edges 23 a control of pendulums 4, 5, arising out of the maximum relief of the coin on the circle engaged by said knife edges, and also a dual control of pendulums 6, '7, arising out. of both the maximum and the minimum relief of the coin on the circle engaged by said knife edges.

The next smallest measuring circle is that engaged by the ends of the pins 30, which are moved outwardly by the coin relief against the pressure of springs 35. That pin 30 which moves the least, as determined by the minimum relief of the coin on the circle engaged by said pins, will limit the movement of flange 32 under the action of springs 59, due to the contact of head 33 with said flange. This limited movement of flange 32 is transmitted through stud 39, contacting with adjustable screw 40, to rock the lever, '41 about its pivot, this applying obviously to 156 to move the flange 48, against which bears theadjustable screw 54 of lever 52. In this way a simultaneous control'of either pendulum 4 or the pendulum 5 is obtained. It will thus be seen that the minimum reliefof the coin on the circle engaged by the pins 30 is availed of to control the movements of both pairs of pendulums 4, 5, and (3, 7.

On the next smallest measuring circle the annular measuring edge 45 of plate 44 makes contact with a'coin, and the degree to which said plate is thus held outwardly, as determined by the maximum relief of the coin on the circle engaged, is available for the control of pendulums 4 or 5, as the case may be. The movement ofplate 44 is transmit.- ted through sleeve 38 to flange 37. The flange 37 carries the member 571, onwhich the lever 52 is pivoted. Consequently there is a shiftingof the pivots of the two levers 51,v with a resultant control of the pendulums 4, 5. Also, this movement of flange 37 is transmitted to the flange 48, against which bears the adjustable screw 54 of lever 52. Therefore simultaneously with the shifting of the pivots of levers 52, there is a rocking of said levers about their pivots, with a consequent control of pendulums 4, 5. It will thus be seen that the maximum relief of'the coin on the measuring circle engaged by the edge 45 is responsible for a dual control over the pendulums 4, 5.

At the innermost point of contact with the coin, namely, that engaged by the center pin 46, the member 49 is pressed outwardly, such motionbeing transmitted through flange 48, contacting with adjustable screw.

54to rock the levers 52 about their pivots. This imposes an additional control on the movements of pendulums 4 and 5. Therefore there is, in connection with the pendulums 4, 5, a control exercised by the plunger portions 22, the pins 30, the plate 44, and the center pin 46, the control due to the plate 44 being a dual control, as described above. Also, in connection with the pendulums 6,

'7, there is exercised a control by the plunger portions 22 and by the pins 30, that by the plunger portions 22 being a dual; control which is responsive both to the maximum and to the minimum relief ofthe coin on the circle engaged by the sectional knife edges23.

In the present embodiment of the invention, applied to a machine of the duplex type, as illustrated in the Keith patent and while for. another coin of the same denomination, but different measurements, such as a twenty-five cent piece of the new coinage, the-other lever 8 will be allowed to rise. In this respect the machine of the present invention partakes of thesame duplex principle as the machines of the Keith patent and my aforesaid copending application. Since, said principle constitutes no part of the present invention, a, detailed elaboration thereof is deemed unnecessary. r
